The westbound A465 Heads of the Valleys road between the Glanbaiden roundabout and the ‘Costain Compound’ temporary roundabout will be closed between 8.30pm on Friday July 7 and 6am on Saturday July 8.

The closure is needed to carry out surfacing work on the newly constructed lanes. It will be well signposted and the official diversion route for westbound traffic only can be seen at: http://ht.ly/7ORM309tf1T

Please note that there are no local diversions available.
